Hi. Usually I would agree to write the noun with small letter. Though I wonder whether Founder in this case couldn´t be considered a title like Elisabeth, Queen of England. I don´t think Queen Elisabeth would be amused if one would considered her a small "q"ueen Elisabeth. Maybe the writer referred to Lim Tean as respected Founder of the political Party. lol or imagine anyone would dare to write: Donald Trump, president of the USA or Mr. president.
